Claims of hearing loss can sometimes result in larger monetary settlements from insurance companies or in the proceedings of litigation.
In addition to malingering of hearing loss, individuals may complain of ear pain, hyperacusis and tinnitus. As hearing loss and tinnitus are subjective conditions, when there is a potential to gain by convincing another group of people that one has these disorders, it is common to encounter individuals claiming to have lost hearing or to have tinnitus. For hearing loss, this is a foolish undertaking, as there are abundant methods of showing that someone actually hears better than they admit.
As is the case for malingering in general, inconsistency between subjective claims and objective measurements is often the key clue. There are many simple methods of detection of an inconsistency between subjective claims of hearing loss (e.g.
Another method of hearing testing that does not require cooperation is the auditory steady state response (ASSR) Attias et al, 2014. A regular audiogram was not very revealing -- often people forget that audiograms basically just test every octave -- if the ear is damaged somewhere other than the tone being tested in that octave -- the audiogram can be normal.
However, a more careful audiogram that covered the frequencies around the tinnitus was abnormal. Audiograms are subjective tests, and in theory at least, someone could pretend not to hear at this frequency. From the combination of the tinnitus match, detailed and careful audiogram, and sweep OAE, it is clear that this patient has objectively confirmed inner ear damage.
Falls are a major problem in the elderly population, but few communications address the influence of anesthesia on balance control.
Elderly patients usually present decreased performance in various neural functions as a result of normal aging of sensorimotor system components and the frequent occurrence of injuries that diminish the dynamic range of functional adjustments [1]. As the elderly population grows, so are the medical aspects that involve this particular group.
Many studies reported postoperative complications, such as postoperative cognitive dysfunction (POCD), myocardial infarction, and deep venous thrombosis [7]. As a criterion for hospital discharge, posturography has been used to evaluate the effect of some specific anesthetic drugs on balance control after minor anesthesia [12,13]. The aim of this study was to evaluate how an anesthetic procedure affects balance control in elderly subjects; we also investigated the differences between patients with and without central vestibular disorders (CVDs) previous to the procedure.
A total of 21 patients being treated in Hospital de Clinicas (School of Medicine), Uruguay, were involved in this study after they gave approval and informed consent to the ethics committee. We evaluated all the patients through a complete medical examination and computed tomography scanning. Posturography was conducted before and 48 hours after surgery, when there was no medical restriction against it. The values of CE and SV for the three groups were compared before and after surgery using the Wilcoxon signed rank test. The group of CVD compensated patients who underwent a GBA (the GBP group), demonstrated significant differences between the pre- and postoperative values, with higher values of COP CE and SV.
In the SP group-CVD compensated patients who underwent an SA procedure-we noted no significant difference in pre- and postoperative balance control values. The range and median of COP CE and SV values obtained for the three groups in both conditions are shown in Figure 1: In accordance with previous reports [14,15], GBN patients (subjects without vestibulo-oculomotor abnormalities) presented balance parameters with less dispersion than in those observed in the groups with ENG abnormalities (the GBP and SP groups), in particular in SV values.
Previous damage to the central nervous system (CNS) is reported as a condition that elevates the risk of post-operative CNS dysfunction, such as spatiotemporal disorientation, POCD, and even delirium [7-10]. A comparison in our patients of the balance parameters measured by static posturography demonstrated that the group with a normal ENG record did not show any change in balance control after a GBA, whereas in the group with vestibulo-oculomotor dysfunctions, ENG revealed worsened balance control parameters, showing these patients to be at risk of falling. Vestibular function is known to decline as part of normal aging, and compensation processes occur to allow correct balance control [22,23].
The audiology community has an immense repertoire of procedures available to it to detect such behavior.

This study reports how a general balanced anesthesia (GBA) and a spinal anesthesia (SA) affect balance control in the elderly. These can be compensated until such patients reach the limit of their physiological reserve, producing clinical or subclinical dysfunctions [2]. Falls are one of the most important issues that affect people aged 65 years or older; reports suggest that nearly 30% of this population fall at least once a year, with multiple causes implicated in their origin [3].
Furthermore, as regards POCD etiology, mental decline prior to anesthesia has been shown to be a risk factor for developing POCD [8-10].
However, at present little is known about how an anesthetic procedure may affect balance control in elderly patients. Previous studies showed how people with abnormal findings in oculomotor control recorded by electronystagmography (ENG) had altered balance control parameters measured with posturography [14,15]. Furthermore, we compared pre- and postoperative balance control in groups with CVD when the procedure was either general balanced anesthesia (GBA) or spinal anesthesia (SA).
All were men 65 years of age or older (mean age, 72 years) who were scheduled for prostate adenectomy for benign prostate hyperplasia. Exclusion criteria were history of vertigo, unsteadiness (or falls), locomotor system alterations, and neurological conditions such as stroke sequela, normotensive hydrocephalus, or severe cognitive dysfunction. The FFR condition is a low-demand situation for subjects' balance control wherein OK stimuli challenge balance control, presenting a sensory conflict situation. According to this, the first element of the vector velocity corresponds to Vxy 2 , and it is associated with the second element of the vector position because the speed with which the subject arrives at the first point is not applicable. The anesthetic procedures were a GBA, defined as a combination of several anesthetics and anesthetic adjuvants, including the use of an inhalational anesthetic [16], or an SA [17]. Range and median values (95% confidence ellipse) of (A) center of pressure area (COPa) and (B) sway velocity (SV) pre- and postoperatively for the normal group (GBN), the group of patients with central vestibular disorders operated under general balanced anesthesia (GBP), and the group of patients with central vestibular disorders operated under spinal anesthesia (SP).
Though little is known about delirium pathophysiology, changes in certain neurotransmitters-in particular acetylcholine and dopamine-are involved in its development [10,19]. Moreover, when the same type of patients underwent surgery with SA, the balance control parameters did not show statistical differences postoperatively. Previous reports measure balance control immediately after the surgical procedure or after administration of a specific anesthetic drug [12,13,24, 25].
We purposefully limit the information on this page, but it isn't difficult to detect malingering.
We divided into three groups, according to electronystagmography findings and type of anesthesia, 21 men older than 65 years (mean age, 72 years) who were scheduled for prostate adenectomy.
Another factor that has been reported are the differences in resultant postoperative morbidity and mortality between general and spinal anesthesia; the spinal approach has been found to be a safer choice in some conditions to avoid such complications [11]. The parameters used as a measure of balance control were the 95% confidence ellipse (CE) of the COP distribution area (COPa) and the COP sway velocity (SV). In CVD compensated patients, there was a larger median and a greater spread of values, with a clear increase of the median after GBA, whereas SA did not have a significant effect.
When CNS damage occurs, some neural intrinsic properties are readjusted to compensate for the altered function. Our results showed that previous subclinical alterations in the vestibulo-oculomotor system may be a condition for developing postoperative imbalance in the elderly population after surgery under GBA.
As a consequence of the administration of anesthetic drugs, an alteration of balance control occurs after a GBA but not after an SA, wherein the effect of the used drugs is restricted to a part of the CNS. We find very interesting that alteration in balance control is still present at 48 hours postoperatively.

Someone who claims to be deaf on audiometry, but has normal OAE tests, is likely to be pretending.
Anesthesia in the elderly requires special considerations in light of an elevated frequency of comorbidities that involve the type of anesthesia and surgery techniques [5,6]. One aspect that has been barely studied is how anesthesia affects balance control in the aged population. Those who had a normal ENG record were classified as normal patients, and those with oculomotor ENG abnormalities were classified as patients with CVDs.
The difference in balance control performance among the three groups can be seen: The GBN group did not show a significant difference before and after surgery.
Vestibular compensation after damage is a classic paradigm of neural plasticity in which, as stated by Xerri et al. We suggest that general anesthetic drugs, interfering with some neurotransmitter systems, affect the changes incurred during the compensation process to restore the function in the vestibulo-oculomotor system. As falls are one of the most relevant health problems in the elderly population, owing to consequences to quality of life and health budget, a suitable approach may be for health care providers to think about appropriate interventions to diminish a patient's postoperative risk of fall, from a pre- and postoperative assessment of balance control such as that proposed by Fujisawa et al. In Lacour M, Toupet M, Denise P (eds), Vestibular Compensation: Facts, Theories and Clinical Perspectives. In another group, designated GBP , were pathological subjects who had clinically compensated central vestibular disorders (CVDs) and underwent surgery under GBA. As the latter group had no history of vertigo, unsteadiness, or falls, we defined their condition as clinically compensated CVD. Conversely, the GBP group showed a significant increase in COPa and SV values after surgery under general anesthesia, whereas the same population operated under spinal anesthesia (SP group) demonstrated no increase in COPa or SV postoperatively. Patients were divided into three groups: One group, designated as GBN (n = 6), contained patients with normal ENG results who were scheduled for prostate adenectomy under GBA. Three different processes are activated to restore an appropriate balance control: activation of silent or secondary pathways, restitution, and substitution. We assessed balance control via static posturography preoperatively and 48 hours postoperatively. In another group, designated GBP (n = 9), patients had clinically compensated CVDs and were scheduled for prostate adenectomy under GBA. These processes involve changes at different levels, such as enhanced synaptic efficacy, silent synapses activation, nerve sprouting, and synaptogenesis, among others. We observed no change in balance control parameters (center of pressure distribution area [COPa] or COP sway velocity [SV]) for those patients in the GBN group or for those in the SP group.
Subjects in the third group, SP (n = 6), had clinically compensated CVDs and were scheduled for surgery under SA.
Vestibular compensation is a distributed process along the CNS [21], and GBA may affect the changes that occur after the process of compensation in the different sensorimotor systems involved in balance control, including the integration centers. We did observe a significant difference for the patients in the GBP group, with higher postoperative values of COPa and SV (Wilcoxon signed rank test).
Our results showed that in subjects with clinically compensated underlying CVD prior to a GBA, balance control worsens after the procedure, whereas no change in balance control occurs after an SA.
Balance control in subjects with normal vestibuloocular function did not change even after a GBA.
